Low voltage mode
When an external emergency power supply is connected to the drive instead of the
normal mains supply, the drive is switched to the low voltage mode based on the
evacuation mode signal from the elevator controller.
Note:
Before the drive can be connected to the external emergency power supply, it
must be at a stopped state and the normal mains supply must be disconnected.
The low voltage mode supports supply voltages in the ranges of
• 48…115 V DC
• 208…240 V AC (3-phase)
• 230 V AC (1-phase).
You can enable the low voltage mode with parameter
LOW VOLT MOD ENA.
Typically, the evacuation mode signal (eg, a hardwired digital input) is connected to
this parameter.
The low voltage mode also introduces parameters
LOW VOLT DC MIN and
LOW VOLT DC MAX for adjusting the minimum and maximum DC voltages,
respectively. The following rules apply:
•
LOW VOLT DC MIN = 250 to 450 V
•
LOW VOLT DC MAX = 350 to 810 V
•
LOW VOLT DC MAX >
LOW VOLT DC MIN + 50 V.
When a low-voltage DC supply, such as a battery, is used, set the value of parameter
BATTERY SUPPLY or its source to 1 (TRUE). With an AC supply, set the value
to 0 (FALSE).
The values in parameters
are effective only when the low voltage mode
is active, that is, parameter
LOW VOLT MOD ENA (or its source) is set to 1.
